Chrome extensions can add useful functionality to the browser, but they can also slow down your browsing experience. We’ve tested the page speed impact of 5,000 Chrome extensions as part of our 2024 report on Chrome extension performance.

Find out what popular extensions increase CPU processing, how some extensions delay page load times, and what difference ad blockers can make.

To add functionality most Chrome extensions need to run code on a website. This will always add additional processing, so this code needs to run as fast as possible and should only run when needed. However, many extensions run this code on every website visit.

Looking at the 336 Chrome extensions with over 1 millions users we find that several add over half a second of additional processing time to every page view.

Monica, an AI tool with 2 million users, adds 1.3 seconds of processing time even on a simple test website. The Read&Write extension with 17 million users adds 0.8 seconds of processing time.
